Using babel package to add Persian text into English document

Question

I'm trying to add some Persian text into an English document (Springer style) using the babel package. Here is my tex file as follow:

\RequirePackage{fix-cm}
\documentclass[smallextended]{svjour3}
\usepackage[utf8]{inputenc}
\usepackage[arabic,farsi,english]{babel}
\begin{document}
\section{introduction}
some Persian text \FR{فروشگاه}
\end{document}

Here is the output:

The issue is that using babel package changed my sections and also figure (table) numbering format (0.1 introduction in this fig). While it is normal 1 introduction when I don't use the babel package (following image).

Answer 1

arabi.ldf (which is dead old ...) is the opinion that every class which is not article should have chapter numbers (and so you get lots of errors).

Add

\expandafter\def\csname [email protected]\endcsname{} 

before loading babel and hope for the best.
